01

Modes of the Major Scale

Seven rotations of the same seven-note parent scale. Each mode uses the same pitch collection from a different tonal center, changing which note feels like home and how the intervals sound against it.

02

Modes of Harmonic Minor

Harmonic minor and its six rotations share a distinctive augmented-second interval and a strong leading tone. Moving the tonal center places those colors in a different part of each mode.

03

Modes of Melodic Minor

The ascending melodic minor scale and its rotations, including Lydian dominant and the altered scale. These sounds are widely used to navigate colorful jazz and fusion harmony.

Pentatonic & Blues Scales

Five- and six-note scales with guitar-friendly shapes. Minor pentatonic is a common first improvising scale; the blues scale adds one chromatic color tone to that foundation.

05

Symmetric Scales

Scales built from recurring interval patterns rather than the uneven step sequence of major and minor scales. Their internal symmetry creates shapes that repeat at regular fret distances.

Exotic & World Scales

Named scales and less-common pitch collections from several musical traditions. Use these pages as accurate fretboard maps and starting points, not as substitutes for learning the traditions they come from.

Ragas & Thaats

Hindustani pitch collections mapped onto the guitar fretboard. These pages show pitch sets and shapes only; complete raga practice also includes characteristic movement, ornamentation, emphasis, and performance grammar.
